| Abstract: |
| Aimed at the problem of silt in the Yellow River water for agricultural drip irrigation, a dish separator is designed and manufactured in accordance with the major characteristics of silt in the Yellow River and the FXJ-150-I hydrocyclone is chosen. The separator and hydrocyclone are arranged in series for separating silt of the Yellow River wa-
ter. Half-content diameter D50 was selected as experimental target, with three-factor quadric orthogonal regression com-posite experimental design, the influences of underlow port diameter, inlet pressure and drum rotation speed were inves-tigated, and a regression equation with high reliability was obtained. The results show that underflow port diameter and inlet pressure have very significant influence on separation efficiency (P<0.01), and drum rotation speed has signifi-cant influence (P<0.05). The optimum parameters are 14mm of underflow port diameter, 0.06 MPa of inlet pressure and 3 800 r/min of drum rotation speed. |
